ADL5506ACBZ-R7

ADL5506 is a complete, low cost subsystem for the measurement of RF signals in the 30MHz to 4.5GHz frequency range, with a typical dynamic range of 45dB, intended for use in a wide variety of wireless terminal devices. It provides a wider dynamic range and better accuracy than is possible using discrete diode detectors. Its high sensitivity allows measurement of low power levels, thus reducing the amount of power that needs to be coupled to the detector. It is essentially a voltage responding device, with a typical dynamic range of 45dB. For convenience, the signal is internally ac-coupled, using a 5pF capacitor and a broadband 50 ohm match, with an external shunt resistor of 52 ohm. This high-pass coupling, with a corner at approximately 19 MHz, determines the lowest operating frequency. It is used in application like RSSI and TSSI for wireless terminal devices, RF transmitter or receiver power measurement, automotive RF bidirectional amplifiers etc.
